Scientists from the University of Maine and San Francisco State University propose to do deck-board incubation experiments in high nutrient, low chlorophyll (HNLC) waters of the eastern (Ocean Station PAPA) and the western (Ocean Station KNOT) Subarctic Pacific Ocean to determine how Fe supply affects phytoplankton species composition. Specifically, this team of scientists plans to address the following specific objectives: (1) assess how the relative availability of Fe bound to weaker and stronger classes of ligands differs among different phytoplankton groups (cyanobacteria, diatoms, dinoflagellates, prymnesiophytes) and how these differences influence the evolution of the phytoplankton community after Fe enrichment in …

Calanoid copepods are key organisms in the California Current (CC) region, consuming primary and secondary production at high rates and serving as prey for larval, juvenile, and small pelagic fish, other invertebrates and certain seabirds. A critical period in the life of several calanoid species is their overwintering period, during which they leave the unproductive surface waters in mid-summer to fall and then ascend to the surface in the springtime, usually coincident with the spring bloom. However, the physical and biological cues that both initiate and terminate the dormant phase of several key copepod species within the CC are poorly …


Alps Implementation Conference, Mary Jane Perry Jul 2008

Alps Implementation Conference, Mary Jane Perry

University of Maine Office of Research Administration: Grant Reports

Intellectual Merit:
A diverse suite of autonomous mobile platforms - including drifters, floats, underwater gliders and AUVs (autonomous underwater vehicles), and the small sensors they carry - have collectively become known as ALPS, i.e., "Autonomous and Lagrangian Platforms and Sensors". A small interdisciplinary workshop is proposed as a follow-on to the Spring 2003 ALPS workshop. The first ALPS workshop convened a group of scientists and engineering, representing diverse backgrounds and interests, who met to identify new science that could best be done with ALPS alone or in conjunction with other platforms; to address technological developments needed to improve the capabilities …


(Rcn) Terrestrial Ecosystem Response To Atmospheric And Climatic Change, Lindsey E. Rustad Feb 2008

(Rcn) Terrestrial Ecosystem Response To Atmospheric And Climatic Change, Lindsey E. Rustad

University of Maine Office of Research Administration: Grant Reports

Future changes in the global carbon balance and associated feedbacks to climate will depend on ecosystem responses to multiple, interacting drivers of global change, such as elevated CO2, temperature, N deposition and changes in the amount and timing of precipitation. Efforts to predict these interactions with modeling approaches have been limited by a lack of relevant experimental data, as well as the absence of mechanisms for rapid communication between modelers and experimentalists. This grant will establish a network of global change scientists in an initiative on Terrestrial Ecosystem Responses to Atmospheric and Climatic Change (TERACC), with the aim to (1) …
